The leadership of three chambers of commerce in San Antonio have joined forces with the San Antonio Restaurant Association, the Real Estate Council and other groups to block a new request for proposals (RFP) for the city’s airport that could lead to union organizing.

Michael Sawaya, who oversees the convention center and the Alamodome and is one of the longest-tenured department heads with the City of San Antonio, has resigned to accept a position at the convention center in New Orleans.

The City Attorney is proposing changes to rules governing protests, parades, and processions that would create an online tool for requesting permits for demonstrations, designate a protest area at the airport, and streamline the permitting process.
